MODIFIED TECHNIQUE OF TRANS-NASAL TRANS-SPHENOIDAL MICRO-DECOMPRESSION FOR PITUITARY ADENOMAS-AN EXPERIENCE.

Background:- Weighing 0.6 grams the pituitary has unassuming regulatory functions on human body and the tumors of pituitary explain the pervasive might of this tiny structure. Patients and methods:- we carried out a prospective comparative study on two patient groups of thirty patients each. One of the groups underwent conventional technique for tumor decompression with xylocaine-adrenaline nasal mucosa infiltration and the other one underwent a modified technique of tumor decompression with normal saline infiltration. In addition we used gelatin foam in empty sella in modified technique in place of fat as is done in conventional surgical procedure.The results of two groups were compared. The patients with tumor infiltration into the sinuses and major vessels were excluded from the study. Results and conclusion:- Modified surgical technique is safe and very effective in terms of in perioperative hemodynamics, blood loss, surgical field and post-operative MRI interpretation.
